Facebook this week released a 6,000-word manifesto, detailing its plans for the future, including how it will use artificial intelligence. In a leaked early addition of the manifesto, Mark Zuckerberg, CEO of Facebook hinted that the firm would use AI to spy on users, in a bid to 'identify risks.' But mysteriously, in the final published version, that information has been removed, suggesting Zuckerberg decided to keep the invasive plans a secret.
